blinker stuck on- update- 99 jeep cherokee classic

I took the car in to be diagnosed and I'm told it's going to need a new wiring harness (it will be about $600 with the diagnosis, parts and
labor). Mechanic said that this would be cheaper than trying to figure out which of the 50+ wires in the area might be damaged.
I suppose these hidden problems often occur when buying a used car but I thought that I had covered my bases by having a 1 hr "bumper to bumper" safety inspection prior to purchasing it.

when i have my headlights turned on, my left blinkers are stuck on but do not blink. when i have my headlights off, my left blinker works fine but the car's
digital clock blinks on and off.
has anyone else had a similar problem? is it something that is difficult to fix? thanks.

You have a rather interesting electrical problem that seems to trace back to the fuse block. Has this car been in a wreck or had any major work done lately, or did it just start happening? It sounds to me as if the panel light circuit is somehow shorted to the left turn signal circuit. It could be happening anywhere in the dash panel circuit as well, which sounds like the probable cause. If the dash TS indicator is somehow shorted to the panel light circuit, that'd do it for sure.
I'm curiously reminded of the home center commercials where the guy puts in a ceiling fan, throws the switch to show off to his old lady, and the sprinklers come on.

I'm not sure if this problem has been going on for awhile or if it just
started- I bought the car used from a private owner last week. The carfax report didn't say that it had been in any accidents. It is possible that the former owner tried to fix it himself because the cover to the fuses is missing.
I take it that this problem is too difficult for a novice like myself to fix? Is it likely to be expensive to repair? Thanks.

There ya go! Bumbling owner tried to fix, couldn't, sold his troubles to someone else. Trouble could be in the fuse block, but could also be up in the dash. What seems to be happening is that the LH turn signal circuit is crossed with the dash light circuit...that's why your digital clock is probably flashing from dim to bright, rather than on and off. First clue: pull the instrument lamp fuse, and the turn sigs may start working.

thanks for the guideance!
will the instrument lamp fuse be labeled in some way?
I also noticed this posting online, in which a person seemed to have a similar problem. do you think (like the discussion below) a bulb could
be a problem or because the clock is flashing there is likely a short.
thanks again

The left turn signal indicator in the dash is stuck ON only when the headlights are turned on. The left turn bulb on the front blinks when turning, but is off otherwise...unlike the right front turn bulb. Are you telling me that the steady left turn signal indicator is telling me to replace the front left turn bulb?

Start by checking / replacing the bulbs on the left side. The turn signal bulbs have two filaments in them. It is possible for one filament to fail, break, and then fall on to the other filament. When this happens all sorts of weird things start happening with the lights.
First thing I would do would be to check those bulbs very carefully for a broken filament or replace them or swap them to the other side and see if the problem goes away (or moves to the other side if you swap them).

You should take the vehicle to an auto electric shop to be diagnosed, not a dealer.
